摘　　要：文章以某一研发项目的车体为研究对象,运用ANSYS软件对仿真分析模型进行模态分析,得到了车体局部固有频率及振型。在模态分析的基础上,对变压器安装的两种方案进行了谐响应分析,并得到了不同频率载荷作用下的结构响应。Taking a car body of one development project as an example,this paper makes modal analysis of the simulation analysis model using the software of ANSYS,and gets the natural frequency and vibration mode of the local part of car body.Based on the modal analysis,it makes harmonic response analysis of two kinds of installation scheme for transformer,and gets the structure response under different frequency force.

关 键 词：车体 模态分析 谐响应分析
